Reply to virtual dj mxl documentation?

i was looking in my virtual dj folders and i saw this file named virtual dj mxl documentations. what is this for? it has tracked and documented every file i have played through my stanton djc.4. everything from the artitst to the release date and comments about the artists. is this being sent to some one or is it so it can map out where the music files are on my computer? im under the assumption its sending out information about what songs i have been playing threw the djc.4 to vdj. can someone please help me understand what this is about?
